Our Reviews of 5 Best Memory Foam Mattresses Without Fiberglass

Highlights

  • 4 firmness options, would work for all sleeping positions and different types of users;
  • sturdy coil support system for reliable performance;
  • special lumbar enhancement to aid proper spinal alignment;
  • strong edges for increased sleeping space;
  • 7 zones for targeted support.

Now, technically, the Winkbeds is not a 100% memory foam mattress without fiberglass. This is a hybrid model that uses a coil support system and foam comfort layers. But those layers are rather thick and work to deliver the same level of cradling most memory foam mattresses do. Plus, the Winkbeds offers an impressive variety of available firmness levels, which means there’s a suitable option for any user.

Fiberglass Explained (And Why It Can Be Found in Memory Foam Mattresses)

Fiberglass is a reinforced polymer material that uses a mixture of both natural and synthetic components like soda ash, silica sand, boron, aluminum, etc. (1). It looks like tiny sparkly glass particles (or fibers) and can be found in many modern memory foam mattresses.

The reason why so many people are concerned with fiberglass is the potential problems it might cause. You see, if fiberglass gets released into your living space, it can cause respiratory issues and skin problems. No wonder, as fiberglass is just tiny glass particles that can stick to almost any surface (including your lungs and skin) and cause damage due to their sharp texture. When sleeping on a mattress that contains fiberglass, you may also start experiencing allergy-like symptoms (eye redness, nose and throat inflammation, coughing, etc.)

So why do manufacturers still use fiberglass in memory foam mattresses these days, even despite its hazardous nature?

The thing is, mattress manufacturers are required by law to ensure a certain level of flame retardancy in every mattress. As foam is highly flammable, adding a fire retardant as a barrier can save one’s life (2). And that’s the purpose of fiberglass, basically.

But here’s the good news:

You don’t have to settle for fiberglass, as there are safer alternatives that can be used as flame retardants. So, you can avoid fiberglass at all and not worry about your mattress safety.

How to Avoid Fiberglass in Mattresses (Plus Safe Alternatives to Look For)

When looking for a memory foam mattress without fiberglass, you need to remember that this material is typically woven into the inner cover of the mattress, so it’s not so easy to spot. Most people find fiberglass in their beds only after removing the mattress cover in order to wash it. In this scenario, the fiberglass releases into the air and covers everything around. It’s extremely hard to clean and often forces people to throw everything away or even move out of the house (3). So, how do you avoid fiberglass in your mattress? Firstly, you need to check the label. Most manufacturers mention the percentage of the materials used. Be aware that some companies mention such alternative fiberglass names as glass wool, glass fiber, or GFK. How to Avoid Fiberglass in Mattresses

Now, you’ve got to be careful here, as not all manufacturers follow this rule. Some of them simply omit to mention fiberglass on the tag. In this case, there are some other things you can do to protect yourself. First of all, pay attention to the cover. Is it removable? If the mattress tag (or website description) specifically mentions that you should not remove the cover, it might indicate that there’s fiberglass underneath.  You might also want to reach customer service and make an inquiry concerning fiberglass. Keep in mind that while mattress companies are obliged to disclose such details, sometimes they can be reluctant to share the information and can be very vague and allusive. If that happens, you should ask them directly what materials they use for the flame barrier. Plus, them being hesitant to disclose the details should be a good indication that their mattress isn’t very safe. It’s also helpful to read other users’ reviews to see whether anyone has found fiberglass in their mattress. There are also some red flags you should be aware of. For instance, if a mattress is overly cheap (under $500), it’s very likely to use affordable fiberglass as a flame barrier instead of safer (and more expensive) alternatives. If a mattress is made in China, it might also be an indication that it contains fiberglass, so you should be extra careful.  Now, while you know how to avoid fiberglass, you should also learn what other flame retardants fiberglass-free mattresses may use. The most common one is wool. It naturally retains moisture and requires significantly higher temperatures to ignite. Wool burns very slowly and gives off minimal heat. It’s also natural and safe, which makes it a great alternative to fiberglass flame barrier. Inherent rayon is another fire barrier material you might come across. Now, let me warn you right away: it isn’t 100% natural. To make a flame retardant, rayon is typically bonded to silica. It’s not fully natural or eco-friendly, but such a fire barrier doesn’t contain extremely harmful chemicals. Another option you may want to consider is latex. Natural latex rubber is also fire-retardant. However, if the mattress isn’t 100% natural, it might still use synthetic flame retardants. So you should pay close attention to the materials used when searching for a good fiberglass-free mattress. Many manufacturers use latex blends these days, as natural latex is quite expensive (4), so it’s always better to inquire about the exact components that go into a latex mattress (and whether it’s 100% natural or combines different material types).

Other Factors to Consider When Looking for a New Fiberglass-Free Memory Foam Mattress: Buyer’s Guide

A good memory foam mattress has to possess more characteristics than just being fiberglass-free. So if you really want to find the best option, you might want to be attentive when shopping and consider some of the most important factors:

  • Firmness level. This aspect is important as it will determine how the mattress would feel. You should choose the firmness level based on your preferred sleeping position. For instance, if you are a back sleeper, you probably need something medium – not overly plush, not too stiff. A medium firmness will allow your hips and buttocks to sink in when lying on your back, but the rest of the body will be supported properly. Side sleepers benefit more from using softer mattresses (or soft-to-medium ones) that offer more cradling for the hips and shoulders. As for stomach sleepers, they need maximum support and minimal (or zero) sinkage (to prevent the spine from curving unnaturally during sleep). Therefore, stomach sleepers are often recommended to choose firmer models. And don’t forget about your weight, as the previously mentioned recommendations work best for average individuals. Lightweight sleepers (less than 130 pounds) should choose slightly softer mattresses for each sleeping position, and heavier users (over 230 pounds) – firmer.
  • Support and thickness. A good mattress should not allow for too much sagging. Instead, it must keep your body supported and spine aligned properly. To achieve that, look for mattresses that have a thick support layer and use high-density foams.
  • Safety certifications. Fiberglass isn’t the only dangerous component you can find in a memory foam mattress. To protect yourself from harmful chemicals, look for at least one of the following certifications: CertiPUR-US, Greenguard (Gold), OEKO-TEX Standard 100, or USDA Organic (5).
  • Durability. Naturally, you don’t want to invest in a mattress that would serve you for a couple of years only. That’s why it’s better to pick something reliable and durable. High-density foams are always better than low-density ones. 
  • Warranty and sleep trial. A free (and long) sleep trial will allow you to test your new mattress and return it for a full refund in case it doesn’t work for you. Keep in mind that many foam mattress sleep trials involve a mandatory break-in period (typically, no more than 30 days). It is required because memory foam needs time to adapt to your body shape. As for the warranty, you should always check what it covers to protect yourself as a customer. A short warranty period can be a good indication that the manufacturer uses mediocre-quality materials and can’t be sure of their mattress’s durability.
  • Temperature regulation. Memory foam is notorious for its heat-trapping properties. Additionally, the material is quite enveloping and can kind of hug your whole body. That can be an issue for hot sleepers. If you want to avoid sweating during the night, choose a mattress that uses open-cell or gel-infused memory foam. Such models tend to sleep neutral, and some might even have a pleasant cooling effect.
  • Motion isolation (for partnered sleep). If you tend to switch positions during the night and don’t want to disturb your partner, you might want to check good motion-isolating mattresses. Memory foam absorbs shock from motion quite well and works great for restless couples, but a mattress might have a bit of a bounce if the transition layer is made of polyurethane foam.

F.A.Q.

Do all memory foam mattresses contain fiberglass?

No, there are safe fiberglass alternatives and many foam mattress companies that use those.

Why do they put fiberglass in mattresses?

Fiberglass serves as a fire barrier and can slow down the burning in case of a fire. It is a safety precaution.

Why is fiberglass bad?

When fiberglass particles are released into the air, they can get pretty much everywhere, including your skin and lungs. Those particles are tiny, sharp, and may irritate skin and cause damage to one’s body.

How do I clean a mattress with fiberglass?

If your mattress label says you shouldn’t take the cover off, you must follow that recommendation. In this case, it’s better to only spot clean your mattress.

What should I do if fiberglass is released into the room?

If you damaged your mattress cover, the fiberglass might start escaping through it, so you should cover the hole immediately (using plastic wrap, for example) and remove the mattress from your home. It might be challenging to clean all the fiberglass particles from your house, so you might need to call a professional cleaning company.

Wrapping Up

As it turns out, finding a good mattress without fiberglass is not such a difficult task. You just need to be attentive to the labels and do your research. Do not hesitate to reach out to customer service and ask them directly about what they use as a fire barrier. And don’t neglect other shoppers’ reviews, as they can give you an idea of what to watch out for when shopping for a new mattress.

If you are still a bit hesitant, allow me to recommend a mattress that managed to win me over. I am talking about the Winkbeds hybrid that uses both memory foam and a coil support system. And it’s safe to say that this model combines the best from the two worlds. It delivers reliable support but feels super comfy and cradling. Plus, there are 4 firmness options available, which means almost any user can achieve their perfect comfort levels during sleep. And let’s not forget about the special zoned support system. With the Winkbeds mattress, you can be sure that your back health will be taken care of.
